Abstract
The invention relates to a Membrane Stirling Engine. The inventors propose a Membrane Stirling Engine, with working gas, with a hot part and with a cold part, where the working gas of the Stirling engine is found both in its hot part as well as its cold part in the membrane skins, which have two ends, whereby they are closed on one end hermetically and on the other end they are open, where they lead into the hot or cold space of a regenerator chamber with their open end tightly sealed.

Membrane Stirling engine, with a working gas, with a hot part and with a cold part, where the working gas of the Stirling engine both in its hot part as well as in its cold part is found in membrane skins, which have two ends respectively, with one end hermetically closed and at the other end are open, which, with its open ends seal, finally leads into the hot or cold room of a regenerator chamber.
Membrane Stirling engine, according to one of the preceding claims, characterized in that the pressure-resistant housing is provided with resources on its hot side as well as on its cold side (such as hydraulic cylinders, bellows, hydraulic cushions and the like), the periodic movement of which pushes the working gas from the membrane skins periodically from hot to cold and the other way around through the heat-transmitting liquid (hydrostatic fluid coupling), whereby there is a flow through the regenerator, with alternating direction of flow.
Membrane Stirling engine as per one of the preceding claims, characterized in that the heat exchange is effected by hot or cold fluid by the membrane skins, into the working gas, by the pulsating of the membrane skins, thereby causing a periodic reversal of the gas flow direction with corresponding mixing of the gas and also that the thickness of the membrane chamber periodically goes to zero, which leads to particularly high heat transfer values (micro-heat exchangers).
Membrane Stirling engine, as per one of the preceding claims, characterized in that the membranes consist of an elastometer, especially silicone and/or polyurethane, which is heat-resistant up to over 200° C. continuously, and that water is used as liquid immersion at temperatures over 100° C. under pressure.
Membrane Stirling engine as per one of the preceding claims, characterized in that the membrane leak tightness in the hermetic bag regenerator as working gas helium or hydrogen are used.
Membrane Stirling engine as per one of the preceding claims, characterized in that the membrane skins are formed by cylindrical hoses, where these are preferably fiber-wrapped so that they are pressure-resistant in filled state and can be collapsed with hydrostatic power.
Membrane Stirling engine as per one of the preceding claims, characterized in that the displacement function of the heat and force-transmitting liquid is generated by sound waves, which are generated by piezoelectric transducers or loudspeaker membranes, which are embedded in the liquid.
Membrane Stirling engine, in particular, in accordance with one of the above claims, characterized in that a membrane Stirling Engine is used for isothermal compression and storage of gases.
Membrane Stirling engine, in particular, in accordance with one of the above claims, characterized in that pulsating gas-filled membrane bags serve as liquid-gas heat exchangers in a heat-exchanging and force-transmitting liquid immersion.
Membrane Stirling engine, which is characterized in that the membrane skins are filled with liquid by means of hydraulic pressure pumps periodically, and while doing so, the gas found in the pressure container is also compressed isothermally (isothermal air vessel).
